FullCalendarJs allows you to save multiple XML feeds into a calendar id and display those calendar’s as if they were one. 
The plugin works specifically off of a jquery plugin. The Jquery plugin is written by Adam Shaw. This plugin is lightweight 
 and is designed for ease of use and simplification. Why bloat your own database with calendar events when you can fetch 
 them all from Google Calendar.
More features to come.
